Factory making Germanium Lenses - Undoped YAG Crystals – Dien

Undoped Yttrium Aluminium Garnet (Y3Al5O12 or YAG) is a new substrate and optical material that can be used for both UV and IR optics. It is particularly useful for high-temperature and high-energy applications. The mechanical and chemical stability of YAG is similar to that of Sapphire.
Advantages of Undoped YAG:
• High thermal conductivity, 10 times better than glasses
• Extremely hard and durable
• Non-birefringence
• Stable mechanical and chemical properties
• High bulk damage threshold
• High index of refraction, facilitating low aberration lens design
Features:
• Transmission in 0.25-5.0 mm, no absorption in 2-3 mm
• High thermal conductivity
• High index of refraction and Non-birefringence
